The McKee Craft Freedom 24 FS/CC 2008 is a deep-V design and the McKee Craft Marathon 184 CC 2008 is a modified-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
The power gap is worth calling out. Rated to 400 hp, the McKee Craft Freedom 24 FS/CC 2008 has a 225-hp advantage over the McKee Craft Marathon 184 CC 2008's 175-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the McKee Craft Freedom 24 FS/CC 2008 carries 180 gallons versus 65 gallons in the McKee Craft Marathon 184 CC 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The McKee Craft Freedom 24 FS/CC 2008 is rated for 10 passengers, while the McKee Craft Marathon 184 CC 2008 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the McKee Craft Freedom 24 FS/CC 2008 could be the deciding factor.
Bottom line: Choose the McKee Craft Freedom 24 FS/CC 2008 if your priority is putting more people on the water - it handles 10 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The McKee Craft Marathon 184 CC 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
